BACKGROUND Field of the Invention

The present invention relates to a hard luggage case, and more particularly to a hard luggage case with an integrally formed bottom portion for mounting of wheels.

Related Prior Art

As shown in FIGS. 1 and 2, a conventional hard luggage case 1 includes a front shell 3 and a rear shell 4 which are connected by a zipper 2. Each of the front and rear shells 3, 4 is provided with wheels 5. The wheels 5 are disposed on the front and rear shells 3, 4 which are independent structures from each other, therefore, the height positions of the wheels 5 are difficult to control during the assembling process, which will cause wobbling of the wheels 5 when the assembling of the hard luggage case 1 is completed. Therefore, a wheel mounting seat capable of covering the bottom of the hard luggage case 1 is used to improve the accuracy of installation of the wheels 5. However, the wheel mounting seat is still an independent structure, the bottom of the

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

DETAILED DESCRIPTION

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIGS. 3-15, a hard luggage case in accordance with the preferred embodiment of the present invention comprises: a case body 10, a cover 40, a connecting assembly, and four wheels 50.

The case body 10 includes a top portion 100, a bottom portion 101, a left lateral portion 102, a right lateral portion 103, a connecting portion 31 and a back portion 104. The top portion 100 and the bottom portion 101 are connected to the left lateral portion 102, the right lateral portion 103 and the back portion 104. The connecting portion 31 is connected to the left lateral portion 102, the right lateral portion 103 and the bottom portion 101. The height of the connecting portion 31 is smaller than that of the back portion 104, so as to form an opening 11 above the connecting portion 31. The case body 10 includes an inner space 12, and the opening 11 communicates with the inner space 12. The bottom portion 101 is an independent unitary structure and includes a plurality of connecting ends 32, and each of the connecting ends 32 is in the form of a cavity formed at each of the four corners of the bottom portion 101. The back portion 104 is provided with a draw bar 20.

In this embodiment, the connecting portion 31 extends horizontally outwards from the bottom portion 101 by a width W and then extends upwards by a height H, as shown in FIGS. 9-13, an arc-shaped concave portion 120 is located at lower end of each of two lateral edges of the opening 11 to connect the connecting portion 31.

The cover 40 is pivoted to the edge of the opening 11 of the case body 10 by the connecting assembly 41. The design of the arc-shaped concave portion 120 greatly facilitates the assembling of the cover 40, and the connecting assembly 41 can be disposed at different positions according to the direction the cover 40 opens. For example, as shown in FIGS. 8 and 9, the cover 40 can be side open or top open, and the connecting assembly 41 can be a zipper. As shown in FIGS. 6-9, the connecting assembly 41 is disposed around the peripheral edge of the cover 40 and the opening 11 of the case body 10. As shown in FIGS. 10-12, the connecting assembly 41 can be a clip assembly which includes a plurality of clipping pieces and clipping rings disposed at corresponding positions on the cover 40 and the case body 10. Or as shown in FIGS. 13-14, the connecting assembly 41 can be a magnetic assembly which includes pairs of magnets (or magnets and objects attracted to magnetically attractive objects, such as iron metal) disposed at corresponding positions on the cover 40 and the case body 10. Or as shown in FIG. 15, the connecting assembly 41 includes a locking member 411 and a retaining seat 412 disposed at corresponding positions on the cover 40 and the case body 10. The locking member 411 can be a combination lock which cannot be opened unless a correct sequence of numbers is known.

The four wheels 50 are disposed at the four connecting ends 32 of the bottom portion 101.

The key characteristic of the present invention is the improvement to the case body 10. The case body 10 is an integral structure, there is the connecting portion 31 of H height at the lower end of the opening 11 to connect the bottom portion 101. The four connecting ends 32 of the bottom portion 101 are in the form of cavities which have the same depth, and each of the connecting ends 32 is provided with the same wheel 50, so that the wheels 50 can be maintained at the same level.

Besides, since the case body 10 is an integral unitary structure provided with the connecting portion 31, the design of the connecting portion 31 can improve the anti-collision strength of the case body 10, strengthen the structure strength of the bottom portion 101 of the case body 10, and enable the luggage case to stand firmly without falling.

Furthermore, the inner space 12 of the case body 10 is provided for carry objects, the draw bar 20 allows the user to pull the luggage case, and the cover 40 is connected to the edge of the opening 11 by the connecting assembly 41. The connecting assembly 41 ensures that the cover 40 is locked to the case body 10, which prevents the opening of the cover 40 during transportation of the luggage case, consequently preventing dropping of the objects from the inner space 12 of the case body 10.

When the luggage case is big, with the wheels 50 directly mounted to the bottom portion 101 of the case body 10, forces will all be acted directly on the wheels 50, which improves the stability and smoothness when the case body 10 moves or stands upright. The luggage case is less likely to fall or tilt over since the ground contact area is increased. Besides, since the bottom portion 101 covers the wheels 50 of the case body 10, the bottom structure strength of the case body 10 is strengthened.

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
